Constructor Detail

XSLChoose

public XSLChoose()

Method Detail

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class StyleElement

Returns:

true - it is an instruction

getReturnedItemType

protected ItemType getReturnedItemType()

Determine the type of item returned by this instruction (only relevant if it is an instruction).

Overrides:

getReturnedItemType in class StyleElement

Returns:

the item type returned

prepareAttributes

public void prepareAttributes()
                       throws XPathException

Description copied from class: StyleElement

Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Specified by:

prepareAttributes in class StyleElement

Throws:

XPathException

validate

public void validate()
              throws XPathException

Description copied from class: StyleElement

Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:

validate in class StyleElement

Throws:

XPathException

markTailCalls

public void markTailCalls()

Mark tail-recursive calls on templates and functions.

Overrides:

markTailCalls in class StyleElement

compile

public Expression compile(Executable exec)
                   throws XPathException

Description copied from class: StyleElement

Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.

Specified by:

compile in class StyleElement

Returns:

either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.

Throws:

XPathException
